SPECIFICATION forming part of Letters Patent No. 494,368, dated March 28, 1893. Application lcd September 8, 1892. Serial N 445,297. (No model.)

'by a channel the width of the anger is entin the forward movement of the machine.

The invention also consists in the means employed. to impart to Said auger a longitudinally reciprocating, as well as a rotary movenient, further in the manner et supporting said anger admitting et its vertical adjustment, and. still lnrther in the peculiar construction, arrangement and combination of parte, as more fully hereinafter described.-

In the drawings Figure l is a vertical, longitudinal section through my machine on line' 'ck-.e Fig. 2. Fig. is a plan view. Figf 1e a detail section online g/*jj Fig." l, and Fig. is an elevation of the parte shown in Fig'. 3 at right angles thereto.

The frame of the machine is oomnos'ed ol' longitudinal sills Land crosseills A mounted on the truck wheels l l.

C is arranger or worm jonrnalcd at its upper end in a box D (pivotally Secured between the sills A,) and extendingr downward therefrom, inclined toward the rear is ,journaledat its lower end in the movable bearing box IC.

ll is a Shoe vertically adjuetahlysecured to the lrame in any suitable manner, such as hyv the bail l1", screw-threaded rod and adjustingnnt ll, the latter helngjournaledin a bearing ll upon the frame and provided with a hand-wheel '.l l"'.

lil is a link pivelally Secured at one end to the shoe l?, and at the other end to the hoi; F.

I is a cross head secured to thoshal't of the anger C near its upper end and carrying- `the anti-friction rollers .il

K isa circular plate havingr a cam track upon which the roller-SJ are adapted to bear, said plate being secured eitherdireetlyto the; frame or preferably to the ripper side of the' pivotal box D. l

L is a beveled gear on the ripper end of the auger shaft `and isan intermeshingbeveled gear on the shaft N, jounaled at the outer end of the jointed frame 0,.,

P is a yoke frame holding the gear M and N in mesh.-

Q is a shield creasing en the upper side oi the' anger forming onits upper edge a tile chute W.

In practice the machine is especially adapt ed for use in laying tile pipe, and may be driven either by horse or steam power. I ho worin C in first lowered to the required depth by adjusting the handle yligand motion is then communicated thereto either from one of the truck wheels, or as shown in the drawings from. a small steam engine or other motor having suitable sprocket and chain connection with the shaft N on the jointed frame O. The anger C is revolved in a direction to force it into the earth, but the rollers .i on the cros's head I in passing over the cam tracli'h alternately raise and lowerlhc angershaft.(which movement is permitted by the link E) thereby causing' a scraping action, loosening,n the earth which le then carried op hy the Worm and thrown to one 'linie reciproeating movement et t-iieauger eliaftrooeefnotin any Way interfere with the operation of the ccnnectinggearing-a5 the jointed frame 0 will admit of cit-her a vertical or horizont-al movement of the shaft-N, while the yoke trarne AlD holds said shaftl in fixed relation to the auger shaft. The shoe li resting; on the hoitoin of the ditch forms a support for the box E, pre ventinpr the anger from being forced haci@ ward, hut not interfering with its reelprometn ing movement on account of the vilira'tory connectingr link Alll'.

The depth of the ditch is .regulated justine the hand wheel liz, and thereby in;r or lowering the shoe ae desired, the pivotal bearing i) allowing the anger shaft to aasumc any angle.

"What .l claim ,as my invention is-y l. 1n a ditching' machine, the combination with the truck. cian inclincdaugersiippertcd by ad XOO :ieeeee therefrom, means for rotating seid. enger end ineens for imparting a longitudinal reciprocating movement to said auger, substantially es described. i

2. In a. ditching machine, the combination with the true-lc and supporting freine, of an inclined anger pivotelly jonrnaleil at its upper end anni leuloported in e verticallyadjust able bearing et its lower enrl and Ineens for imparting' a, rote-ry and reciprocating movement to eaid anger, substantially as described.

3. In zi ditching machine, the combination with ille truolr sind supporting frame, ,of en inclined angerjonrnnled in e. pivotal bearing at its upper end end. e vertieeily adjustable bearing et its; lower enfl, moans; for roleiingg seid enger, and ineens for imparting e longitndineliy reciprocating movement thereto, substantially ee described. el. Inv ditching machine the combination with the truck and supporting frame, of en inclined vertically reciprocating enger journeled in e pivotal bearing at its vupper end and in e movebie bearing at its lower end, a shoe veiiioelly odjnembly supported from ille freine and e lienible conneetion between Seid shoe end :newbie bee-ring, subeieniielly :is described.

In 'testimony whereof l affix my signature in presence of two witneseee.
